This disclosure relates to an infant calming, sleep promoting and SIDS preventing device.

BACKGROUND

Persistent crying and poor infant sleep are perennial and ubiquitous causes of parent frustration. During the first months of life, babies fuss/cry an average of about 2 hours/day and wake two to three times a night. One in six infants is brought to a medical professional for evaluation for sleep/cry issues.

Infant crying and parental exhaustion are often demoralizing and directly link to marital conflict, anger towards the baby and impaired job performance. In addition, they are primary triggers for a cascade of serious/fatal health sequelae, including postpartum depression (which affects about 15% of all mothers and about 25 to 50% of their partners), breastfeeding failure, child abuse and neglect, infanticide, suicide, unsafe sleeping practices, SIDS/suffocation, cigarette smoking, excessive doctor visits, overtreatment of infants with medication, automobile accidents, dysfunctional bonding, and perhaps maternal and infant obesity.

Traditional parenting practices have utilized swaddling, rhythmic motion and certain sounds to soothe fussing infants and promote sleep (by reducing sleep latency and increasing sleep efficiency). “Sleep latency” may be defined as the length of time between going to bed and falling asleep. “Sleep efficiency” may be defined as the ratio of time spent asleep (total sleep time) to the amount of time spent in bed.

Swaddling, rhythmic motion and certain sounds imitate elements of a baby's in utero sensory milieu and activate a suite of subcortical reflexes, called the “calming reflex,” during the first 4-6 months of a baby's life. After that time, these stimuli can still promote infant sleep, but they do so by activating a conditioned response.

Swaddling is a method of snug wrapping with the arms restrained at the baby's sides. This imitates the confinement babies experience in the womb and the continual touch they experience from the soft lining of the uterine walls. Swaddling also inhibits startling and flailing, which often interrupts sleep and starts/exacerbates crying.

Rhythmic, jiggling motion replicates the movement fetuses experience when the mother is walking. The motion stimulates the vestibular apparatus in the semicircular canals of the inner ear. A specific, rumbling noise imitates the sound created by the turbulence of the blood flowing through the uterine and umbilical arteries. In utero, the sound level babies hear has been measured at between 75 and 92 dB. Each baby has a specific and distinctive unique mix of motion and sound that most efficiently activates his or her calming reflex. This preferred mix stays consistent through the first months of life (i.e. babies who respond best to swaddling plus jiggling continue to respond to those modalities over time and don't abruptly switch their preference to swaddling plus sound).

The calming reflex has several constant characteristics. It is triggered by a stereotypical sensory input; produces a stereotypical behavioral output; demonstrates a threshold phenomenon (i.e. stimuli that are too mild may not be sufficient to activate a response); has a threshold that varies between individuals (i.e. is higher or lower for any given child); the threshold varies by state (e.g. fussing and crying raise the level of stimulation required to exceed threshold and bring about reflex activation); the reflex is almost irresistible at first, but wanes after 3-4 months of age.

Since the nominal level of a stimulus needed to reach the triggering threshold of the calming reflex differs from one child to the next, failure to exceed a particular child's threshold level often results in a total absence of a calming response. For example, slow smooth motion may calm one upset infant, yet be too subdued to calm another. Likewise, moderately loud sound (e.g., at a level of about 78 dB) sound may reach the calming threshold for one child, but be insufficient to calm another. Once triggered, the stereotypical output of the calming reflex is a reduction of motor output and a more tranquil state (quiet alert state or sleep). In this context, the word “state” describes an infant's level of attention to and interaction with the environment. Infants experience at least six identifiable states in this context: quiet sleep, active sleep, drowsiness, quiet alert, fussing and crying. The intensity of sound and motion needed to trigger any particular baby's calming reflex is substantially greater than the levels needed to keep the calming reflex activated.

However, despite the convenience, efficacy and availability of swaddling, rhythmic motion and sound, these methods fail to calm and promote sleep in a large portion of the infant population because they are not being applied correctly. When parents fail to reduce infant crying and promote sleep, they often bring the baby into their own bed. However, this is problematic because sharing a bed with a parent has been proven to raise an infant's risk of Sudden Infant Death Syndrome (SIDS) and accidental suffocation (which the US Centers for Disease Control reports has been increasing by 14% per year for approximately twenty years). The hazard of bed sharing is further elevated if the parent is extremely fatigued. Like inebriation, exhaustion reduces adult judgment and responsiveness. As many as 50% of new parents report sleeping fewer than 6 hours/night, the level demonstrated in adults to cause a level of impairment of attention and cognition comparable to inebriation. For this reason, bed sharing with an exhausted parent increases the SIDS risk and the suffocation risk (from accidental overlaying of the parents body over the infant's head, pulling bedding over the baby, etc.).

Other behaviors that stressed, exhausted parents engage in also directly raise the risk of SIDS and suffocation (e.g. cigarette smoking, cessation of breast feeding, falling asleep with the baby on a couch, placing the baby on the stomach to sleep). Medical authorities recommend parents avoid bed sharing. However, cribs too can be problematic. Babies sleeping supine in cribs have a higher risk of plagiocephaly (flattening of the skull), which may require expensive and inconvenient medical treatment, and may result in permanent deformity. A crib's flat, quiet, nonmoving surface is devoid of the swaddling, rhythmic motion and sound that can activate the calming reflex or conditioned response and reduce crying and sleep latency and increase sleep efficiency.

In an attempt to improve infant sleep in cribs, parents have employed several methods (prone sleeping, swaddling, rocking motion, sound), however each is problematic. For example, the prone position is associated with a 3-4 fold increased risk of SIDS. Unswaddled babies can roll to the stomach position (prone), which is associated with an 8-19 fold increased risk of SIDS. Swaddled babies can roll prone, which is associated with a 12-fold increased risk of SIDS. Rocking motion delivery systems (e.g. swings, cradles and hammocks) may all present problems. The motion of infant swings is often insufficient to calm a fussy baby and induce sleep. When sitting in a swing, a baby's head can roll forward and create an airway obstruction, leading to death. Cradles and hammocks require parents to be the motion-powering energy source, and thus can be done for only a limited part of the sleep period. Also, they can accidentally cause a supine baby to roll to the side or stomach or become wedged into the side wall of the sleeper. Sound delivery devices (e.g. fans, air filters, hair driers, sound machines and white noise CDs) may be cumbersome and expensive and the volume, quality or frequency profile of the sound they produce may be excessive or too different from in utero sound to be effective.

Over the past twenty years, attempts have been made to engineer technological methods to create infant calming/sleep devices to deliver sound and motion more conveniently. These current infant calming/sleep devices typically deliver fixed and unchangeable motion and sound. This is a problem because each baby has a different mix of sound and motion that most efficiently calms the child's crying. For example, some babies respond best to swaddling plus motion, while others are not calmed unless they have swaddling, motion plus white noise sound. Another problem with fixed motion and sound infant calming/sleep devices is that each baby has a unique level of motion and sound that induces calming and sleep most efficiently. For example, slow rocking may reduce sleep latency for one infant, yet be too subdued to do so in another infant. And, quiet sound may be sufficient to increase sleep efficiency for one baby, but not another. Devices that deliver constant sound may also expose a baby to unhealthy levels of sound, if they are set at too high a volume.

Still another problem with fixed motion and sound infant calming/sleep devices is that the intensity of the stimuli needed to activate the calming reflex and induce calm and sleep varies substantially as a child's state changes. For example, most fussy babies require more vigorous, jiggling motion (with rapid acceleration-deceleration) and more vigorous sound inputs (as loud as a vacuum cleaner or hair drier—75 to 95 dB). On the other hand, calm, sleepy babies need less vigorous inputs. Further, current infant calming/sleep devices do not continue all night long; do not deliver optimal sound and motion for triggering the calming reflex; do not increase and decrease their sensory input in a step-wise fashion to vary the sensory input intensity to give the baby the most effective level of stimulation with the minimum exposure to high levels of sound; lack the ability to gradually increased the sensory input over the first weeks of life and to gradually wean a baby off the stimuli as he or she ages.

In addition, crib death or SIDS (Sudden Infant Death Syndrome) is a leading cause of infant mortality. Approximately 2500 US babies die each year from SIDS during the first year of life. The peak occurrence is from 2-4 months of age, with 80% of the victims being under 4 months and 90% being under 6 months of age.

In the 1990's a program to reduce SIDS deaths called “Back to Sleep” was introduced. At that time, it was discovered that sleeping on the stomach was a key triggering factor in SIDS, so caregivers were instructed to place babies on their backs for sleeping. Within less than a decade, the rate of SIDS dropped in half, however, since that time, the SIDS incidence has been not diminished. Furthermore, while the exact cause of SIDS is unknown, the primary cause is believed to be immaturity of the breathing regulatory system in the brain. In essence, it seems that babies “forget” to breath and their internal alarm system does not reliably arouse them to recommence breathing. Once breathing stops, the body becomes more and more hypoxemic and acidotic, leading to a downward spiral of reduced heart rate, dropping blood pressure, cardiovascular collapse and death. Studies have indicated that the risk of stomach sleeping may indeed predispose babies to SIDS by reducing infant arousability.

In the hospital setting, the use of an infant monitor immediately alerts the healthcare workers if an infant stops breathing. The health care workers can often resuscitate the infant with simple stimulation (e.g. vigorous jiggling), without the need of oxygen or formal CPR.

In the home setting, however, studies have not shown that using a cardiorespiratory monitor reduces the incidence of SIDS. This lack of effect may be because, 1) the parent responding to the alarm may not know how to resuscitate the baby; 2) the parent may be panicked and incapable of resuscitating the baby; 3) the baby may be so hypoxic and acidotic, that, by time the parent arrives at the scene, an irreversible cardiorespiratory collapse has already been precipitated.

However, a device that can begin vigorous stimulation of the baby within seconds of the baby stopping breathing (apnea) may be able to arouse the minimally depressed baby and reinitiate the breathing sequence before a downward cardiovascular spiral has occurred. The “Back to Sleep” program has proven that simple interventions can lead to a profound reduction in mortality by virtue of helping babies be slightly more aroused, as they are in the supine position. In other words, it may not take a great amount of sensory input maintain the baby in a mode of regular breathing or to return the baby to normal breathing after a brief, transient cessation. Also, two studies have shown that supine swaddling is associated with a reduction in SIDS. Swaddling has been shown to increase arousability, especially during active sleep.

Therefore, a need exists for an infant calming/sleep system that overcomes or minimizes the above-mentioned problems.

SUMMARY

This disclosure is generally directed to devices and methods for aiding calming and safe sleep of an infant. In embodiments, an infant calming/sleep-aid device is provided that includes a main moving platform that moves in a variable manner with accompanying variable sound generation, each adapted to calm a baby, induce sleep, and maintain sleep. This device can be independently controlled, from the device itself, or via communication with a mobile device application that also delivers users various forms of information about sleep, their baby, etc. Also, a secure sleep sack design may be provided which prevents accidental rolling to the potentially risky prone position. Furthermore, this device may contain a sensor to monitor one or more of the baby's biometrics to detect when the baby has temporarily stopped breathing. In that case, the device will sound an alarm to summons the caregiver and commence vigorous motion and sound—similar to the intervention used by medical personnel to arouse apneic infants in the hospital—before the baby becomes acidotic and bradycardic. The device can also be programmed by the parent to call 911 or local emergency services in case of cessation of breathing of the infant.

In one embodiment, an infant calming/sleep-aid device is provided that includes a main moving platform that moves in a reciprocating manner. An actuator drives the reciprocating movement of the main moving platform. An optional moving head platform may be linked to the main moving platform to reciprocate in response to reciprocating movement of the main moving platform. In some embodiments, at least one of a motion sensing device and a sound sensing device are, respectively, at or proximate to main moving platform or the moving head platform. A logic system links at least one of the motion sensing device and the sound sensing device to the main moving platform, whereby signals detected by at least one of the motion sensing device and the sound sensing device cause the logic circuit to modulate the movement of the main moving platform and the intensity of the sound produced by the sound generation system.

In some embodiments, the infant calming/sleep-aid device includes a rigid base and a main movement linkage or bearing extending from the base. A moving infant support is mounted on the main movement linkage or bearing, whereby the platform is movable on the main movement linkage or bearing relative to the base. An actuation assembly that controls movement of the moving platform about the main movement linkage or bearing relative to the rigid base includes an actuator mounted to the rigid base.

In some embodiments, a method for aiding the calming of a fussy infant or the sleep of an infant, includes the step of moving the infant on the platform in a reciprocating or rotating manner about an axis that intersects the infant at a 90° angle to a major plane of the surface supporting the infant, repetitively moving the supporting surface up and down, a combination of such movements, or others. For example, motion of the platform in other planes in addition to a horizontal plane, such as a swinging motion, or rotating motion around a horizontal axis, is also possible.

The movements may be made in an adaptive manner. In some embodiments, at least one of a sound generated by a sound generating device and a reciprocating or repetitive or rotating movement may be modulated in an updating and adaptive matter by a logic circuit-controlled actuation in response to at least one of the sound of the infant and the motion of the platform. In embodiments, sound may delivered to an infant in the device but not motion if the infant is not securely attached to the platform. In embodiments, motion may delivered to an infant in the device but not sound, at the parents choice.

The device and method have many advantages. For example, the device and method provide for modulation of the movement of an infant in an updating and adaptive manner. The rapidly accelerating and decelerating motion of the device, which induces the infant's head to accelerate and decelerate over a short distance in a safe and specifically controlled manner, imitates the sensations that babies experience before birth in the womb. During the first 6 months of an infant's life these sensations induce the infant's natural calming reflex. In addition, after just days to weeks of time, these cues begin to trigger a conditioned response. The device's specifically designed motion and sound, along with its adaptive control system reduce irritability during awake time and improve infant sleep (specifically reducing irritability during periods of sleep, reducing sleep latency and increasing sleep efficiency) for babies up to at least twelve months of age.

As further steps to reduce SIDS, the infant calming/sleep system described herein may provide babies with a secure swaddle or sleep sack, as two studies have shown that a supine swaddle may reduce SIDS. The secure sleep sack described herein is intended to: 1) prevent overheating; 2) promote greater air flow; 3) prevent accidental rolling to the stomach when the baby is unsupervised. A sensor to detect when the baby stops breathing to cue/trigger a vigorous response and the sending of an alarm to parent may also be included in the infant calming/sleep system. This sensor can cue or trigger a rapid response of vigorous motion/sound and generate an alarm to summons the caregiver or send an automatic message to call for emergency medical services, such as via a WIFI connection.

In embodiments, a method for preventing SIDS includes the steps of providing a sleep device comprising a platform for supporting an infant; monitoring the infant with a sensor that generates a signal indicative of at least one of a motor status or a physiologic status of the infant; receiving and analyzing, by a control system of the sleep device, the generated signal indicative of the motor status or the physiologic status of the infant; generating, by the control system of the sleep device, at least one output that controls at least one of a motion of the platform and a sound directed to the infant if a distressed status of the infant is detected based on the analyzed signal; and generating at least one of reciprocating motion of the platform and a sound directed to the infant in response to the at least one output.

DETAILED DESCRIPTION

In an exemplary embodiment, shown in FIGS. 1 through 6, infant calming/sleep-aid device 10 includes an enclosure 12 about an infant 14. Enclosure 12 surrounds main moving platform 16. Main moving platform 16 may be made from wood-based particleboard with an injection molded support tray or the entire platform may be injection molded. The injection molded support tray may provide stiffening ribs, attaching features, and the like. As can be seen in FIG. 2, main moving platform 16 includes base 18, moving head platform 19, padding 20 and cloth covering 22. Secure sleep sack fastening straps 24 extend from main moving platform 16 for securing infant 14 in suitable secure sleep sack 26. As can be seen in FIG. 2a , sleep sack fastening straps may take other forms such as attachment clips and may be integral to the sleep sack 26. This embodiment includes a head pad insert 28 that supports the head of infant 14. Preferably, head pad insert 28 includes a gel in order to reduce the risk of plagiocephaly. Handles 30 extend laterally from main moving platform 16. Main moving platform 16 is supported and rotatable about a main support shaft (not shown) that is fixed to rigid base 32. Rigid base 32 may be made from molded plastic, stamped metal, and the like. Control panel 34, which includes speed control knobs 35, status lights 37 and controls 39 for microphone 38. Rigid base control electronics 36 may include drive electronics of the infant calming/sleep-aid device 10, as well as other sensors, such as an accelerometer or biometric sensor (not shown).

In another representative view of infant calming/sleep-aid device 10 of FIG. 2, shown in FIG. 3, main moving platform 16 is supported by main support shaft 40 at main rotation bearing 42, Moving head platform 19 supports head pad insert 28 and is rotatable about head rotation bearing 46 through arm 48 extending between head rotation bearing 46 and moving head platform 19. Motion sensing device 50, such as an accelerometer, at moving head platform 44 detects motion of moving head platform 19. Microphones 38 at moving head platform 19 detect sound emitted by the infant (not shown) when supported by infant aid sleep device 10. Speakers 52, supported by brackets 54 mounted on rigid base 18, are located directly beneath moving head platform 19. Springs 56 linking either side of moving head platform 19 to main moving platform 16 dampen motion of moving head platform 19 relative to main moving platform 16 during reciprocal motion of moving head platform 19 induced by reciprocating motion of main moving platform 16.

Reciprocating motion of main moving platform 16 about main support shaft 40 is about an axis that is orthogonal to a major plane of main moving platform 16. Reciprocating motion of main moving platform 16 is driven by actuator assembly 58.

In some embodiments, the body and the head of the infant can be out of phase. For example, at relatively slow speeds, the motion of the head of the infant can be in the same direction as that of the motion of the upper body of the infant. At relatively high speeds, the reciprocal motion of the head of the infant can be in the opposite direction as that of the upper body of the infant. In another embodiment of the invention (not shown), reciprocal motion of the head of the infant can be in some other direction, such as orthogonally relative to the plane of the main support platform.

Actuator assembly 58 includes drive motor 60 mounted to rigid base 32 and gear assembly 62 linked to drive motor 60 and also mounted to rigid base 32. Drive motor 60 may be an electric motor with a reciprocating drive disk and push/pull rod.

Actuation of drive motor 60 causes rotation gear assembly 62 to drive eccentric drive plate 64 about an axis normal to a major plane of rigid base 32, Eccentric drive plate 64 is linked to swing arm plate 66 of actuator assembly 58 that extends from eccentric drive plate 64 to rod end 68 of screw 70 and is pivotally mounted to rod end 68 of screw 70. Screw 70 is mounted to amplitude modulation assembly 72. Amplitude modulation assembly 72 includes amplitude modulation motor 74, nut 76, mounted on nut frame 78, which swivels on rotation bearing 80 mounted to rigid base 32. The axis of rotation of nut frame 78 on rotation bearing 80 is, like that of eccentric drive plate 64, normal to a major plane of rigid base 32. Actuation of amplitude modulation assembly 72 causes movement of screw 70 along its major longitudinal axis to thereby cause rod end 68 to become more proximate or less proximate to amplitude modulation assembly 72. Arm 82 extends from an end of screw 70 opposite to rod end 68 to elastic actuator catch bracket 84, which is mounted on base 18 of main moving platform 16. Arm 82 extends through an opening defined by elastic actuator catch bracket 84 and is linked to main moving platform 16 by springs 86, 88 held in place on either side of elastic actuator catch bracket 84 by nuts 90, 92, respectively.

Actuation of actuation assembly drive motor 60 causes rotation of eccentric drive plate 64 about an axis normal to a major plane of rigid base 32 which, in turn, causes reciprocal motion of swing arm plate 66 roughly along a major longitudinal axis of swing arm plate 66, Such reciprocal motion of swing arm plate 66 causes rod end 68 to move in a reciprocal motion from side-to-side of a major longitudinal axis of screw 70 which causes reciprocal rotation of nut frame 78 about an axis normal to major plane rigid base 18 and side-to-side motion of the opposite end of screw 70 opposite that of rod end 68 of screw 70. Such side-to-side movements of the opposite end of screw 70 causes reciprocal longitudinal movement of arm 82 extending through the opening defined by elastic actuator catch bracket 84.

Resistance to such reciprocal motion of arm 82 causes alternating reciprocal compression and relaxation of springs 86, 88, which thereby causes reciprocal motion of main moving platform 16 about main support shaft 40 linking main moving platform 16 to rigid base 32.

The amplitude of reciprocal motion of main moving platform 16 about main support shaft 40 is controlled by the location of screw 70 relative to amplitude modulation assembly 72. For example, if actuation of amplitude modulation assembly 72 causes rod end 68 to become more proximate to amplitude modulation assembly 72, the side-to-side motion of the opposite end of screw 70 will become greater, thereby causing the amplification of reciprocal motion of main moving platform 16 about main support shaft 40 to increase. Conversely, actuation of amplitude modulation assembly 72 to cause rod end 68 of screw 70 to become more remote from amplitude modulation assembly 72 will diminish the side-to-side motion of opposite end of screw 70, thereby reducing the amplitude of reciprocal motion of main moving platform 16 about main support shaft 40.

Reciprocal motion of main moving platform 16 may cause a delayed reciprocal motion of moving head platform 44 about head rotation bearing 46. The reciprocal motion of moving head platform 44, although delayed, may have greater amplitude about main support shaft 40 because of the rotation of moving head platform 44 about head rotation bearing 46. However, the amplitude of reciprocal motion of moving head platform 44 about head rotation bearing 46 may be dampened by springs 56.

Nevertheless, the reciprocal motion of main moving platform 16 and moving head platform 44 about main support shaft 40 is measured by motion sensing device 50 at moving head platform 44. Measurements by motion sensing device 50 are relayed back to control panel 34 and rigid base control electronics 36 which, alone, or optionally, in combination with external computer software programming, modulate actuator assembly drive motor 60 and amplitude modulation motor 74. Motion detection by motion sensing device 50 can also, optionally, modulate computer programming to affect selection and volume of sounds emitted by speakers 52. Microphones 38, in addition, or optionally, receive acoustical signals that can be fed back through rigid base control electronics 36 or/and control panel 34 to software, either on-board or remote from infant calming/sleep-aid device 10, that further modulates actuator assembly drive motor 60, amplitude modulation motor 74 and/or sounds emitted from speakers 52. Various control algorithms associated with modulation of actuator assembly drive motor 60, amplitude modulation motor 74 and speakers 52 will be more fully discussed below.

In one embodiment, the device allows for a reciprocating motion at 0.5-1.5 cycles per second (cps) of ˜2″ excursions, but if the baby is fussy the device responds by delivering a smaller excursion (e.g. <1.3″) at a faster rate (˜2-4.5 cps). This fast and small motion delivers the specific degree of rapid acceleration-deceleration force to the semicircular canals in the vestibular mechanism of the inner ear that is required to activate the calming reflex.

Also, the reciprocating motion typically has a maximum amplitude of less than 1.3 inches during the rapid phase of motion (−2-4.5 cps), further ensuring safety of the infant.

In one embodiment, the biometric sensor monitors the infant and generates a signal indicative of a respiration status or a cardiovascular status of the infant, such as to detect when the baby has paused breathing for a predetermined period or time, or has a cardiovascular collapse, such as indicated by a heart rate below a predetermined threshold, or the like. The sensor signal can be fed back through rigid base control electronics 36 or/and control panel 34 to a control system such as software, either on-board or remote from infant calming/sleep-aid device 10. The control system may receive and analyze the signal to determine whether a distressed status of the infant exists, and further may act, such as to generate an output to control modulation of the actuator assembly drive motor 60, amplitude modulation motor 74, or generate a telephone call to emergency services via Wi-Fi connection, and/or generate alerting and stimulating sounds that may be emitted from speakers 52. An alarm can be directed to the infant's caretakers as well.

In some embodiments, in response to detection of infant distress, both vigorous motion of the platform and a loud sound can be provided. For example, providing motion of the platform at a frequency greater than 0.5 Hz and an amplitude that is greater than 1 inch, along with sound having an intensity of at least 65 dB, may provide appropriate stimulation of the infant, Of course, other amounts of stimulation are also envisioned.

FIG. 6A illustrates an exemplary and non-limiting embodiment of a drive motor 60. Drive motor 60 may include motor case 600, motor 602, motor gear 603, motor case bottom 604, release button 606, button springs 616, screw 608, contact pin 610, metal plate 612, and the like. Motor case 600 may be made from an acrylonitrile butadiene styrene (ABS) plastic and the like. Motor 602 may be a 12V 300 RPM motor and the like. Motor gear may be made from polyoxymethylene (POM) plastic and the like. Motor case bottom 604 may be made from ABS plastic and the like. Release button 606 may be made from ABS plastic and the like. Button spring 616 may be made from stainless steel and the like. Screw 608 may be M3 HEX flat head 15 mm long screw, made from stainless steel, and the like. Contact pin 610 may be made from stainless steel and the like. Metal plate 612 may be made from stainless steel and the like.

FIG. 6B illustrates the drive motor location 614 of the drive motor 60 in an embodiment of the infant calming/sleep-aid device 2258. FIG. 6C illustrates a cross sectional view of an embodiment of the infant calming device/sleep-aid device showing the drive motor.

In another embodiment, shown in FIGS. 7 through 9 calming/sleep-aid device 100 includes actuator assembly 102, which substitutes for actuator assembly 58 of the embodiment shown in FIGS. 2 through 6. Specifically, as shown in FIGS. 7 through 9, drive motor 104 of calming/sleep-aid device 100 is linked to bearing 106, which is, in turn, leads to the eccentric drive plate 108. Eccentric drive plate 108 is connected to push/pull rod 110 that extends through an opening defined by elastic actuator catch bracket 112, Springs 114 about push/pull rod 110 link push/pull rod 110 to main moving platform 16 through elastic actuator catch bracket 112. Springs 114 are series elastic actuator push-springs; they transfer force from actuator assembly 102 to catch bracket 112. Balancing dampers 115 beneath push/pull rod 110 dampen the motion of moving platform 16. Springs 117 are pull-balancing springs; they pull on bracket 112 in parallel with balancing dampers 115 to create the desired smooth sinusoidal motion of moving platform 16 at low frequencies and the more square wave, rapid accelerating/decelerating motion at high frequencies. Injection-molded plastic features that are parts of the main moving platform 16 may be used to create the desired smooth sinusoidal motion of main moving platform 16 at low frequencies and the rapid accelerating/decelerating motion at high frequencies.

Actuation of drive motor 104 causes reciprocal longitudinal movement of push/pull rod 110 through the opening defined by elastic actuator catch bracket 112 and translates that reciprocal movement into reciprocal motion of main moving platform 16 about main rotation bearing 42, as does reciprocal motion of arm 82 through elastic actuator catch bracket 84 of the embodiment shown in FIGS. 2 through 6. Other components of the embodiments shown in FIGS. 7 through 9 operate in the same manner as those of infant calming/sleep-aid device 10 represented in FIGS. 2 through 6.

As shown FIG. 10, software control system 120 receives various inputs from a variety of sensors or control input devices representing desired settings or the like and, based on one or more of these inputs, acts to control one or more of various devices, such as to control sound, motion, and/or lights of the sleep aid device, or to initiate an emergency call or alarm. As shown, the control system 120 processes inputs from microphones 125, from speed control knob 121 (also shown as element 35 in FIG. 2), and from a three-axis USB accelerometer 123 (represented as motion sensing device 50 in FIG. 3), and from a biometric sensor 1002, such as a wireless sensor for detecting one or more of cardiac and respiratory status. Control system 120 generates one or more output signals, such as to control speakers 131 (speakers 52 as shown in FIG. 3), and to multichannel USB motor controller 122, which controls actuator assembly drive motor (such as drive motor 60 shown in FIG. 3) and amplitude modulation motor (motor 73 of FIG. 3 or drive motor 104 of FIG. 7-9). Status lights, such as tricolor USB DEs 121 (or lights 37 such as shown in FIG. 3) can also be controlled. Logic or control modules of software control system 120 can be located on-board or remotely from the embodiments of infant calming/sleep-aid devices 10, 100 shown in FIGS. 2 through 9. The modules may include a crying detection module 124 that receives data from microphones 125, and relays to a behavior state machine module 126 whether or not an infant on infant calming/sleep-aid device is crying or not crying. Microphones 125 may be mounted on the infant calming/sleep-aid device, integrated into the infant calming/sleep-aid device, included in a sensor that is placed on or attached to the infant, and the like. Biometric sensor module 1002 may relay one or more of an infant's physiologic parameters (e.g., breathing status, temperature, motion status, etc.) to the behavior state module 126, or depending on the signal provided by the sensor, directly to a Wi-Fi control Module 1004, Depending upon the input received by behavior state machine module 126, output signals will control motion generation module 128 or audio generation module 130 or a Wi-Fi phone connection module 1004. Alternatively, or in addition, output signals from behavior state machine module 126 will modulate generation of audio data output from audio generation module 130 to speakers 131, represented as speakers 52 in FIGS. 2 through 9.

Motion generation module 128 receives input from speed control knob 121 and information regarding motion of the device 10, 100 from motion analysis module 132. Actuation of motion generation module 128 will modulate the actuator assemblies of the embodiments shown in FIGS. 2 through 9.

Data received from accelerometer 123 is processed by motion analysis module 132 to thereby modulate the actuator assembly through motion generation module 128 and/or audio generation module 130 to thereby control the actuators assemblies or speakers, respectively. In addition, motion analysis module 132 controls status light module 134 to alert, through the status lights, whether motions of the main moving platform and the head platform are nominal or not nominal, or alternatively, through feedback, soothing or not soothing to the infant. “Nominal”, as that term is defined herein, refers to any and all motion for which the filtered acceleration signal does not exceed a specified, or predetermined maximum motion threshold for a specific length of time. The process by which the motion analysis module classifies motion as nominal or not nominal is detailed in FIG. 12 and in the accompanying text below.

In one embodiment, the rate of the reciprocating rotation is controlled to be within a range of between about one and about four and one-half cycles per second (cps) and with an amplitude of the reciprocating motion at a center of a head of the infant of between about 0.2 inches and about 1.3 inches. In anther embodiment, the rate of reciprocating motion is within a range of between about 0.5 and about 1.5 cycles per second and an amplitude of the reciprocating rotation at a center of the head of the infant is in a range of between about 0.25 inches and about 2.0 inches. In differing embodiments, this motion may be parallel to, or orthogonal to the platform supporting the infant's body and head.

In embodiments, the control system 120 may operate in a manner wherein the intensity of maximum stimulation is increased over the course of the first weeks and subsequently weans the infant off the device's motion by incorporating the infant age as a variable used in the behavior state module 126, For example, modulation of motion and/or sound may be further controlled by at least one of the weight of the infant, the age of the infant, and the duration of the detected sounds made by the infant.

Referring to FIG. 11, crying detection module 124 receives audio data from the microphones of infant calming/sleep-aid devices 10, 100, which is processed through a digital band-pass filter 136 to generate filtered audio data. Energy-based threshold 138 receives filtered audio data to determine whether the audio energy is over threshold or under threshold. Time-based filter 140 receives data from energy-based threshold 138 to provide an indication as to whether the infant is crying or not crying. The information, as discussed above with respect to software control system 120 (FIG. 10), is received from crying detection module 124 by behavior state machine module 126 that will then provide signals to control motion generation module 128 or audio generation module 130 or both.

Motion analysis module 132, shown and represented in more detail in FIG. 12, receives a signal from the motion-sensing device of infant calming/sleep-aid devices 10, 100, at digital filter bank 142. Digital filter bank 142 filters the signal to generate a filtered motion amplitude estimate that is used as input to motion generation module 128 (FIG. 10). In addition, the filtered motion amplitude estimate passes through a range check 144 to determine whether the motion is within a soothing or known soothing range, which is provided to time-based filter 146 and provides an indication as to whether a motion is soothing or not soothing to motion generation module 128 (FIG. 10).

Filtered motion sensor, or accelerometer, data from digital filter bank 142 also passes through threshold crossing-based motion frequency estimator 148 to provide an estimate of motion frequency, which is provides to motion generation module 128.

Outputted data from threshold-crossing-based motion frequency estimator 148 also passes through range check 144 for indicating whether the motion is or is not soothing.

Filtered accelerometer data from digital filter bank 142 also is processed to determine whether or not the acceleration exceeds a specific maximum motion threshold 150 and, depending on the result, processes that data through time-based filter 152 to provide an indication as to whether the motion is nominal or not nominal. This indication as to whether the motion is nominal or not nominal is used as input to motion generation module 128 (FIG. 10), and is additionally used to control status lights 37 (FIG. 2) via status light module 134 (FIG. 10).

As can be seen in FIG. 13, behavior state machine module 126 receives information from crying detection module 124 (FIG. 11) as to whether the infant is in a state of crying or not crying. This information is used by the state machine's state transition rules 156 to select an active state from a library of states 154, thereby outputting a desired motion state, a desired audio track and/or desired volume/equalizer settings to audio generation module 130 of FIG. 10.

As can be seen in FIG. 13a , behavior state machine module 126 receives information from biometric sensor module 1002 (FIG. 10) as to whether a biometric measure is normal or not normal. One possible biometric measure may be normal if an infant is breathing, not normal if an infant is not breathing, and the like. This information is used by the state machine's state transition rules 156 to select an active state from a library of states 154, thereby outputting a desired motion state, a desired audio track and/or desired volume/equalizer settings, a desired phone call state, and the like to audio generation module 130 (FIG. 10). Desired alarm state may be a parent alarm state and the like. Desired audio track may be a special vigorous white noise track and the like. Desired phone call state may be initiate Wi-Fi phone call to emergency services and the like.

Audio generation module 130, represented in FIG. 14, receives signals of a desired audio track and desired volume/equalizer settings from behavior state machine module 126 (FIG. 10) and signals of motion analysis, specifically, whether the motion is nominal or not nominal, from motion analysis module 132 (FIG. 10). Desired audio track may be a sound audio track, music audio track, special vigorous white sound audio track, and the like. Audio generation module 130 includes a special vigorous white noise audio track 161, a library of “soothing” audio tracks 160, a digital equalizer/volume control 162 and alarm sound 164. Upon receipt of a new command from motion analysis module 132 (FIG. 10), audio generation module 130 will cross-fade to a desired audio track and volume, and crossfade to desired equalizer settings. If the motion is not nominal, then an alarm signal may be output to override the audio signal with an alarm. The audio signal from the audio generation module 130 (FIG. 10) is output to the USB speakers 131 (FIG. 10) of infant calming/sleep-aid device 10, 100.

At baseline, the audio generator will produce an output of a low-pitch, rumbling sound at about 65 dB to 74 dB. Upon receipt of a new command from crying detection module 124 (FIG. 11), audio generation module 130 will cross-fade to a more high pitched audio track and louder volume, at about 75 dB to 95 dB.

Upon receipt of a new command from behavior state module 126 (FIG. 10), audio generation module 130 will cross-fade to a desired audio track and volume, and crossfade to desired equalizer settings. If the signal received from the behavior state module 126 is indicative of an abnormal biometric signal that has been detected by the biometric sensor 1002 (FIG. 10), for example that an infant is not breathing, then an alarm signal and special vigorous white sound audio track will be output to override the audio signal with an alarm and special vigorous white sound audio track. The special vigorous white sound audio track signal from the audio generation module 130 (FIG. 10) is output to the USB speakers 131 (FIG. 10) of infant calming/sleep-aid device 10, 100.

Audio generation module 130 (FIG. 14) receives signals from the biometric sensor module 1002 (FIG. 10). An abnormal reading, such as a reading indicating that an infant is not breathing, will activate a desired audio track, such as a special vigorous white sound audio track, parent alarm and desired volume/equalizer settings. Upon receipt of a new command from biometric sensor module 1002 (FIG. 10), audio generation module 130 will cross-fade to a desired audio track and volume, and crossfade to desired equalizer settings.

Audio generation module 130 (FIG. 14) may receive mild signals that indicate an infant is awakening. Mild signals may detect that an infant is mildly awakened. Mild signals may be mild motion signals, mild sound signals, and the like. Mild signals may be sent from a sensor attached to or worn by an infant. Mild signals may be detected from an infant before the infant begins to cry. Audio generation module 130 (FIG. 14) may begin to increase sound levels when mild signals are received.

Two variations of motion generation module are represented in FIGS. 15 and 16. In the first embodiment of motion generation module 128, shown in FIG. 10, motion generation module 128 receives a desired motion state input from behavior state machine module 126 (FIG. 10), a motion frequency/amplitude signal from motion analysis module 132 (FIG. 10), a desired system speed signal from speed control knob 121 (FIG. 10), and a signal as to whether a motion is nominal or is not nominal. The “desired system speed” is the setting of speed control knob 121, whereby the operator can select or limit the motions allowed by infant calming/sleep-aid device 10, 100. The desired motion state signal goes to lookup within motion generation module 128, which outputs a reference motor command based on a desired motion state. If the currently active motor commands are close to the reference motor commands, then the motor commands are actively adjusted within an allowable envelope via a gradient ascent based on observed motion frequency and amplitude. If the current motor commands are not close to the reference motor commands, then the motion generation module will set desired motor commands via path planning in a motor command space. “Path planning” transitions motor settings to desired motor settings by inserting intermediate motor settings as necessitated by nest dynamics to ensure that motion stays in a desirable range during transition. If the desired system speed is less than “full,” then a signal is sent to adjust the desired motor commands in proportion to the desired system speed. “Full” is the fully-on position of the knob, and means that infant calming/sleep-aid device 10, 100 is not being limited by this knob and is allowed to perform all of the motions it determines to be relevant. If speed control knob 121 is turned down from “full,” motions of infant calming/sleep-aid device 10, 100 start to become constrained, so speed control knob 121 acts as an operator to override the normal motion behavior of infant calming/sleep-aid device 10, 100. If not, then a comparison is made as to whether the observed motion is nominal. If it is not, then motor output is disabled. If it is nominal, then an output signal of desired motor commands is given to target motor positions and speeds of the actuator of the multichannel USB motor controller. In some embodiments, sound is delivered to an infant but not motion if an infant is in the device but not securely attached. The level of motion and or sound output may also be modified by the parents' choice of a special boost function.

In an alternative embodiment of motion generation module 128, shown in FIG. 16, there is no receipt by the module of signals related to motion frequency and amplitude. Therefore, it is only necessary to set desired motor commands by interpolating from a current command based on a look up table of motor commands based on a desired motion state in response to receiving a signal with respect to the desired motion state. All of the other components of motion generation are the same as represented in FIG. 15.

In one embodiment, the motion generation module 128 receives a motion state input of an abnormal signal, for example that an infant is not breathing, from the biometric sensor module 1002 (FIG. 10). The resultant programmed vigorous motion may continue until the abnormal biometric signal is discontinued, for example when an infant begins breathing again, or the device is shut off.

Another exemplary embodiment of an infant calming device is shown in FIGS. 17-21. In this example, the infant calming device includes a main moving platform with an integral head support portion, that is, the head support portion is contiguous with and rigidly fixed to the main moving platform, in essence creating a single platform supporting the head and body of the infant.

An enclosure 1702 for an infant calming device using a single main moving platform is shown in FIG. 17. Single main moving platform 2102 and rigid base 2114 of this device are shown in FIGS. 18 and 19, where FIG. 19 also shows the other components of the device, as seen looking through main moving platform 2102. FIG. 20 shows cross sectional views of the embodiment of an infant calming device using a single main moving platform.

As shown in FIG. 21, main moving platform 2102 is supported by main support shaft at main rotation bearing 2106. The main rotation bearing 2106 may be comprised of several vertical pieces of plastic or spring steel that do the job of supporting the upper surface, while also flexing to replace the springs and dampers described above.

Motion sensing device 2108, such as an accelerometer, underneath main platform 2102 detects motion of main platform 2102. Microphones (not shown) detect sound emitted by the infant (not shown) when supported by infant aid sleep device. Speakers 2110, supported by brackets 2112 mounted on rigid base 2114, may be located directly beneath head position of infant on main moving platform 2102. Secure sleep sack fastening clips may be attached to main moving platform 2102 for securing an infant in suitable swaddling clothes.

The exemplary embodiment shown in FIGS. 17-21 operates similarly to the embodiment shown in FIGS. 1-16, described above. The embodiment in FIGS. 17-21 differs from that shown in FIGS. 1-16 in that the separate head and body boards are replaced by a single moving board. Along with the replacement of the separate head and body boards by a single moving board, the secure sleep sack fastening straps are replaced by clips integral to the baby swaddle wrap. The head rotation bearing, rotating head platform, head board support U bracket, head balancing extension spring, and weight sensors are also absent.

In embodiments, the main moving platform 16, 2102 may hang from the framing that is above the main moving platform via fabric and/or cables. The main moving platform 16, 2102 would then be free to rotate or swing as needed. A motor and offset wheel would deliver the needed input to create the desired motion, such as a smooth sinusoidal motion of the main moving platform at low frequencies and the rapid accelerating motion at high frequencies.

As discussed above, two versions of the infant calming/sleep-aid device are shown in FIGS. 2 through 9, with microphones to detect infant crying, motion and sound actuators, a swaddling system to keep the baby in optimal position and a gel pad to reduce the pressure on the back of the skull (thereby avoiding possible plagiocephaly). The device also may contain a logic board to accomplish two tasks; delivering staged interventions of specially engineered sound and delivering motion created by two linked platforms attached to a motor and rod actuator (as well as a series of springs and dampeners to modulate the activity.) These platforms may act in a reciprocating manner about an axis that intersects the infant and is orthogonal to a major plane of the surface supporting the infant to provide a motion that varies from slow smooth rocking (0.5-1.5 cps) to keep babies calm- and promote sleep, and ramping up to a faster, smaller, jiggling motion (2-4.5 cps) with a more spiked waveform to deliver a sufficiently abrupt acceleration-deceleration action to stimulate the vestibular mechanism of the inner ear, trigger a calming reflex and soothe the baby, such as when the baby cries (e.g, head rocking back and forth in excursions of less than F). The sound in the device may be adapted to respond to the baby's upset by starting a specially engineered high pitched sound, then stepping down to quieter, lower pitched white noise over several minutes. A wide variety of sound patterns may be enabled. The device may be adapted to gradually increase the intensity of the sound and/or motion during the early weeks of life and to gradually reduce (i.e. wean) the intensity of the sound and/or motion over a suitable time period, such as several weeks or several months later in infancy.

Another exemplary embodiment of an infant calming/sleep-aid device is shown in FIGS. 22 through 27.

As shown in FIG. 22, infant calming/sleep-aid device 2258 may include various control system related components including a software control system 2216 for receiving and processing inputs 2200 and generating outputs 2246, a user interface 2204, and a communication facility 2214. Components of the software control system and the user interface can be located on-board or remotely from the enclosure/platform portion of infant calming/sleep-aid device 2258. Inputs 2200 may include data or control signals from various types of sensors or devices such as microphone or sound sensor 2202, motion control sensor 2206, accelerometer or motion sensor 2208, user interface 2204, biometric sensor, and the like. Outputs from the control system 2216 are directed to devices such as speakers 2248 for controlling the generation of sound, motion controller 2250 for controlling the motion of a platform or structure on which the infant is placed, Wi-Fi phone call to emergency services, and status light facility 2252 for controlling illumination of various status lights.

Other inputs may also be provided by other sensors such as visual sensors, including cameras, pressure sensors, sensors located in a swaddle or sleep sack, third party sensors, including monitors, sensors embedded in fabrics, and the like. Sensors embedded in fabrics may be flexible sensors. Sensors may be used for detecting child physiological parameters.

The weight of the infant may be input manually or automatically. The weight of the infant may be input automatically from a scale that is integrated with the infant calming/sleep-aid device 2258. The user interface 2204 may be used to provide a diary. The diary may be a sleep diary, cry diary, and the like. The user interface 2204 may be used to boost baseline stimulation by providing more motion and sound. For example, an extra fast and/or strong sound could be provided for infants that are difficult to calm. This extra fast and/or strong sound could be called Intervention4. Intervention4 may only be able to be activated two consecutive times, until the device is reset. Intervention4 may be limited to about two minutes of operation. The infant calming/sleep aid device may turn off after Intervention4 has been operating for about two minutes.

User interface 2204 may be an integral part of the infant calming/sleep-aid device 2258, or a separate piece, such as on a mobile peripheral device, which may be connected by a wired connection, a wireless connection, and the like to the infant calming/sleep aid device 2258. The wireless connection may be a Wi-Fi connection, Bluetooth connection, and the like.

The user interface 2204 may have controls, set-up information input, and other input data that can be sent to the software control system of the device. Controls may include an on/off control, sound control, motion control, light control, and the like. Controls may be enabled or disabled. Motion control may have an extension option that automatically extends the sound, extends the basic motion of the device, and the like. The option that extends the basic motion of the device may be used after an infant is older than four months. Light control may have a dim option, be used to turn and LED alarm light on or off, and the like.

Infant calming/sleep aid device 2258 may provide a mechanism to activate the calming reflex of an infant, such as via the control system described with respect to FIG. 22. The mechanism may use stereotypical sensory input, stereotypical behavioral output, and the like to trigger the calming reflex. The activation mechanism may be programmed to wane after 3-5 months or the like. The mechanism may exhibit threshold variations that vary between higher and lower thresholds based on the individual infant. The mechanism may vary by biometric evaluation or state of the infant and may call for higher or lower levels of stimulation based on the state of the infant. The state may be a quiet sleeping state, active sleep state, drowsiness state, quiet alert state, fussing state, crying state, and the like. The state may be matched to the optimal stimulus level of an individual infant. Levels may also be adjusted to match the age of the infant, for example during the first month of the life of the infant. Failure to exceed the optimal stimulus level may result in an absence of response by the infant to the mechanism. The mechanism may be activated by sound generated by the infant, movement generated by the infant, abnormal biometric signals, and the like. The output of the mechanism may cause reductions in motor output levels. The infant calming/sleep aid device 2258 may automatically shut down if an infant is not calmed by higher levels of motion and sound. Higher levels of motion and sound may be called Intervention3 and Intervention4. The infant calming/sleep aid device may teach infants to sleep better by training the sleep pattern of the infant using sleep cues. Sleep cues may be swaddling, effective motion, optimal sound, and the like. Motion may take on characteristics of a more square-shaped wave as the platform moves more quickly.

The mechanism to activate the calming reflex or the conditioned response of an infant may be activated by a feedback based control mechanism. The feedback based control mechanism may select modes, parameters, parameter ranges, and the like. Modes may be motion modes, sound modes, and the like.

Devices of the type depicted in this disclosure were tested in the following way: A baby was placed in a swaddling sack (with arms in or out) attached to the mattress of the device and securely laid on his/her back. The device produced a baseline level of low pitched, rumbling noise at approximately 65 dB and baseline motion of a smooth, side-to-side rocking (2 inch excursions to either side). When the baby cried for more than ˜10 seconds, the device responded by playing a specially engineered sound that was harsher, higher pitched, more multi-frequency (75-80 dB) to mimic the intensity of the sound that the baby heard inside the mother's uterus prenatally. (This sound can be measured in situ at up to 92 dB.) If the crying continued another ˜10 seconds (despite the sound), the motion accelerated to a faster, more jiggling action of the head (2-3.5 cps, but no more than 1 inch head excursions to either side). The combination of fast movements delivered with sufficient vigor, the harsh, loud sound, and the secure sleep sack all worked together to activate the calming reflex, in the majority of irritable babies and inducing either calmness or sleep. The device responded to the baby's cry in a step-wise fashion-gradually increasing sound and then motion-to a maximal level. Once the baby was calmed the motion and sound of the device was gradually reduced in a specific, step-wise fashion back to the baseline activity.

Subjects

The device was tested on over twenty babies (12 girls, 10 boys) were in the device. The babies ranged from 5 weeks to 6 months of age. Their weights ranged from 8 pounds to 18 pounds.

Methods and Procedures

The subjects were tested to record their resting and sleeping in the device. The tests usually began when the baby was hungry and tired (immediately before their usual naptime). The time when the baby was last fed and napped was recorded and then the baby was put in the swaddling sack and placed in the device. Data from three accelerometers and a device-mounted camera was recorded to detect the vigor of activity and measure the exact excursions of the baby's head. Each test started with the device set at its lowest level for sound and motion, and the device responded to the baby's cries. The device was allowed to quickly advance through each of its stages as the cries escalated. Once the baby was calmed, the device's motion would slow, in a stepwise fashion, and the loudness and pitch of the sound would decrease, in a stepwise fashion. This format was repeated 2-4 times during sessions with each of the subjects. The first set of studies was done using a prototype with a dual motion actuator and the second set of studies was done with a prototype with a single motion actuator.

Results

During twenty-one tests, 19 babies were either significantly calmed or put to sleep by the device (absence of calming was due to hunger). Most calming and sleep occurred within 2 minutes of placing the baby in the device.

This device is responsive to a baby's needs, such that an infant's upsets are typically soothed by vigorous stimulation to activate the calming reflex, followed by a diminution of those stimuli to help keep the calming reflex turned on and sustain the baby in a calm state and/or promote sleep (i.e. reducing sleep latency and increasing sleep efficiency.

“Sleep latency” may be defined as the length of time between going to bed and falling asleep. “Sleep efficiency” may be defined as the ratio of time spent to the amount of time spent in bed.

It is possible to promote infant calming and sleep through the use of swaddling plus very specific sound and motion stimuli to activate the calming reflex.
